Canon Events — and the Fix for Each

10 things almost every IMG does. They are funny because they are universal — and each one has a specific, boring fix that nobody posts about.

By Dr. Marish Asudani · Published · Updated

What are the most common mistakes IMGs make during USMLE prep?

Almost every IMG makes the same 10 mistakes, and they are ordering problems, not discipline problems. The big ones: rebuilding the plan every week instead of building it backwards from a hard exam date, opening UWorld cold instead of spending 2 to 3 days reading, applying and recalling the system first, taking an NBME before the content is done instead of NBME 27 at the end of it, taking NBMEs online instead of offline in 10 blocks of 20, keeping 2 sets of notes instead of writing everything into First Aid, and waiting until after internship to start.

Every one of these cost me or a student real weeks. The good news: sequence is fixable in an afternoon, and discipline is not.

Read the ones you recognise. Skip the rest.

1 · A new study plan every week

“I made a new study plan again this week, because I fell behind on the last one.”

What is actually wrong: the plan has a daily target but no end date, so every missed day silently inflates tomorrow until the number is impossible and you rebuild from scratch. Rebuilding feels like progress. It is the opposite.

The fix: pick a hard exam date from the hours you can study, build the plan backwards from it once, and let missed days redistribute instead of compounding. The 16-week timeline → · or have it built around your date →

2 · 3 hours of Boards & Beyond, nothing retained

“Great explanation. Where does it live in First Aid?”

What is actually wrong: the teaching is fine. It is not anchored to the book, so you finish with slides and a book and no idea which to annotate — and your UWorld does not move a point.

Boards & Beyond is not a necessity. You don’t need it for every system, and most of you don’t need it at all.

The fix: use something that teaches First Aid itself, then test the page you just read. Why B&B, Kaplan, Rx and Pixorize came off my list → · what replaced them →

3 · Opening UWorld cold

“42% on my first block. I think I’m just not smart enough.”

What is actually wrong: UWorld is a learning and assessment tool, not a first-pass resource. Opened cold it measures nothing except that you have not read the system yet. My own first block was 50%.

The fix: 2 to 3 days on the system first (read it with the First Aid Guide, apply it with Mehlman, recall it with FA Foundation Anki), then blocks of 20 in tutor mode, at least 2 blocks a day, then review every miss back into the First Aid page. The RPSR method → · the whole loop, on renal →

4 · Saving questions for random mode

“I did about 70% of the system. I’ll do the rest later.”

What is actually wrong: the 30% you skipped was not held back — it was never opened. Those are the concepts that appear brand new during revision, when there is no time left to learn them.

The fix: a system ends on a score, not a feeling — every question attempted, every miss traced to its page, and the last 2 blocks above 65 to 70%. The 5-point completion checklist →

5 · Taking an NBME before your content is done

“I took a baseline. It destroyed me for 2 weeks.”

What is actually wrong: forms are limited, and burning one cold, before your systems are finished, gives you a number you cannot act on and a fortnight of doubt you did not need. Even in my own run, 28 was the dip — 75%, between an 83 and an 83.

The fix: your first NBME comes at the end of your content plan, never before. Finish every system, then give it a 7-day NBME week: NBME 26 offline in blocks of 20 for practice, then NBME 27 on day 8 as your first full form. The Vault schedule builds that week for you the moment your content ends. The exact order, 26 through 33 →
▶Before giving your first NBME, watch thisWhen to take it, offline, and the block method.

6 · Taking NBMEs online

“50 questions, 75 minutes. Felt comfortable.”

What is actually wrong: the online format is spacious and inflates your score by 4–6%. You book a date on a number that was never real, and the pace you trained is not the pace of the exam.

The fix: offline, always: same conditions as the real exam, so the score is one you can trust. 10 blocks of 20 questions, 30 minutes each, first pass done by 23. Pair a form with a Free 120 for a true 14-block day, or take the full 14-block Vault assessment. NBMEs offline: the complete system → · taking your first NBME →
▶How to solve NBME blocksThe 2 passes inside every block of 20.

7 · Reading the score and filing the form away

“Got a 68. Onto the next one.”

What is actually wrong: taking another form without harvesting the last one is paying for the same diagnosis twice. The form told you in writing what it will ask again; most people read the number, feel something, and never open it.

The fix: same-day review, blind check, error log by system — the review is the exam. The review protocol → · if the number will not move →

Harvest every form you've givenThe NBME Booster Anki: forms 20 to 34 and the Free 120 as 1-line cards, sorted by system. Opens straight into the deck.

8 · 2 sets of notes

“Lecture notes for college, First Aid for USMLE.”

What is actually wrong: you studied the year once and now have to revise it twice. This is the single most expensive habit on the list, and it compounds for years.

The fix: every extra point goes into the First Aid page. One book at the end. First year to final year → · the final-year version →

9 · “I’ll start after internship”

“There’s no time. I’m on shift.”

What is actually wrong: you are waiting for a clean 6-hour block that is never coming, while 6 hours of dead time already exist inside your shift — unusable because UWorld is on a laptop at home.

The fix: UWorld, First Aid (with the First Aid Guide) and the Sketchy PDFs on your phone. I did the whole of Step 1 in 14 weeks during internship that way. Exactly how →

10 · Restarting on Monday

“This week I’m locking in. For real this time.”

What is actually wrong: prep never collapses in a day. It leaks through quiet zero-days nobody witnesses, and the only person keeping score is you — and you are very easy to negotiate with.

The fix: make the skip visible. A dated plan that chases you twice a day, a board that resets every Monday, and one partner in your exact week. The part nobody plans for → · the accountability system → · how to actually stay consistent →

The pattern underneath all 10

Not one of these is a knowledge problem. Every single one is an ordering problem: the right resource at the wrong time, the right form too early, the right notes in the wrong book. That is why adding resources never fixes any of them — and why 5 resources in the right order beats 40 in the wrong one.
Do this today: pick the one you recognised hardest, open the guide next to it, and fix that single thing. Not all 10. Just 1. Then open usmlevault.com and put a date on the calendar — most of the other 9 quietly die when a real date exists.
Every fix on this page.
None of these are discipline problems.
They are ordering problems. 4 questions and the order gets decided for you.
